When Justin Smith decided that his body wouldn't let him perform up to his own lofty standards, he knew it was time to stop playing.
Smith announced Monday he is retiring after 14 seasons as one of the top defensive linemen in the NFL, dealing yet another blow to the San Francisco 49ers in a rough offseason.
"They all want you to keep playing, and I want to keep playing as well, but when you get on the bald tires, you're on the bald tires," Smith said.
One of the most durable players at one of the most physically demanding positions, Smith had been hampered the past two seasons by a bum left shoulder that he first hurt in training camp in 2013.
That shoulder absorbed the brunt of the punishment as a right defensive end going up against 300-pound linemen, and Smith did not feel up to playing another season.
"It doesn't respond like I want it to respond anymore," he said. "If you don't have the tools, you can't do the job. It's time to go."
Smith had just two sacks in the final 14 games last season as his practice time, snap count and effectiveness dwindled toward the end of the season.
Two other 49ers defensive stars have also retired this offseason in linebackers Patrick Willis and Chris Borland.
... An advisory group appointed by Mayor Kevin Faulconer recommended that the Chargers contribute $300 million toward a new $1.33 billion stadium, with the NFL giving $200 million, the city and county $121 million each and personal seat licenses totaling $120 million.
Under intense pressure from the team and the NFL, the Citizen's Stadium Advisory Group said in its financing plan that there won't be tax increases or increases to the city's general fund, and that the financing plan doesn't rely on development to pay for the stadium, parking or infrastructure.

Minjee Lee wins Kingsmill title
Minjee Lee shook off a three-putt bogey on her first hole with two finishing pars and won the weather-delayed Kingsmill Championship by two shots Monday, her first victory on the LPGA Tour. Lee, an 18-year-old Australian, finished at 15-under 269. She surged into the lead on Sunday with a round highlighted by a five-hole stretch that she played in 5 under and returned to the Kingsmill Resort's River Course on Monday morning with a four-stroke lead.

Pharoah has leisurely day
American Pharoah took a short walk to stretch his legs after his flight before getting a bath and retiring to his barn for some well-earned rest.
